Application server and method to perform hierarchical configurable data manipulation

ABSTRACT

Clients using standard software protocols may access a manipulation application server for manipulation service on data via a number of methods including Internet applications, a Java RMI server, a CORBA gateway server and graphical screen interphase applications. The manipulation server provides manipulation service on the data based on dynamically maintained, centrally stored manipulation functions.

FIELD OF THE INVENTION

The present invention relates to an application properties server and method to provide software manipulation services for clients. More particularly, the present invention relates to a system and a method for allowing applications software using established computer network protocols to execute hierarchical configurable data manipulation from a centralized database.

BACKGROUND OF THE INVENTION

Computer applications (“application servers”) commonly require input data to be manipulated prior to additional processing. The manipulation requirements are often dynamic. For example, manipulation requirements for a telephone service provider's software applications may change based on changed customer service availability, newly available or no longer available customer services, the number of customer requests in a given period, the acceptable times for requests, or the version of the software running.

In today's networked environment, application servers run a variety of different software protocols (e.g., J2EE Containers with CORBA orbs, J2EE Containers with RMI) and typically require a number of different data manipulations before performing other functions. As a result, a need exists for an application server that can dynamically maintain, process and efficiently run manipulations for a plurality of clients running different software protocols simultaneously. A further need exists for solving the common business problem of continually needing to translate, manipulate, or to otherwise conform data that is input by a user or used by an application, prior to further processing or storing of the data, with dynamically maintainable manipulation functions.

Further, because data manipulation requirements often change, a need exists for a manipulation application server that can perform the manipulations run on specific fields of client manipulation requests without requiring extensive changes in software. Most computer software applications use configuration variables to alter its behavior without the need for regenerating code. This is most often done using text files. In today's Internet and networked environments this can cause administrative problems. This is largely because the same software application may be running on several machines, in several locations. Thus, in order to alter uniformly the behavior of all software applications, or clients, all files need to be accessible by the text files. This can cause great expense and significant administration problems. For one thing, security considerations often dictate that a text file employed to alter a software application must be on the same machine that is running the code. Therefore, the configuration file often must be replicated over several machines. If changes are made on one software application, they must also be made on all of the other applications. Errors can occur if the changes are not made consistently on all of the applications. Accordingly, a further need exists for an application server that will allow application server administrators to update the various manipulations done on fields of data without a new release of code.

SUMMARY OF THE INVENTION

The present invention is a system and method wherein application servers using standard software protocols may access a centralized, maintainable, manipulation application server coupled to a data schema for providing manipulation services. The client servers may access the manipulation server via a number of methods including Internet applications, a Java RMI server, a CORBA gateway server and graphical screen interphase applications. The manipulation application server provides manipulation services on the data based on dynamically maintained, centrally stored, manipulation functions, and returns manipulation notifications to, or provides additional services for, the client servers. According to embodiments of the present invention, data is received from user clients, manipulated by an application server via stored, dynamically maintained functions, which are invisible to the user clients, and returned to the user clients for further use or storage.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic diagram of an overview of the present invention.

FIG. 2 shows an illustrative example of a specific embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1, the present invention preferably includes an application properties server 100 for receiving manipulation requests from clients 400 and a storage mass 200 for storing centralized manipulation functions and data. As will be appreciated by those skilled in the art, manipulation properties application server 100 may be represented by one or more servers, even if located in different geographic locations. In the preferred embodiment of the present invention, depending on system resources, a number n of clients 400 may access the manipulation application server 100 for manipulation service via a number of methods including, for example, clients 401 using Internet applications, clients 402 using Java via a Java RMI server (not shown), clients 403 using CORBA via a CORBA gateway server (not shown), and clients using graphical screen interphase applications.

Referring to FIG. 1, according to an embodiment of the present invention, clients send manipulation requests to the application server 100 which then accesses storage mass 200 using a hierarchical rule-based system 500 (FIG. 2). The manipulation application server 100 identifies and accesses the stored data and performs manipulation services associated with the manipulation requests. Preferably tables of manipulation functions, or rules, implement the manipulation data, which may preferably be stored in a storage mass such as an Oracle database. As described hereinbelow, by utilizing a table-based storage system, the application server of the present invention can efficiently and dynamically perform manipulation services on manipulation requests provided by a number n of clients.

Referring to FIG. 1, client 401 requests manipulated services related to data for, for example, long distance ordering information such as valid installation dates, available installation dates, the allowable number of telephones, etc. Storage mass 200 contains a plurality of data tables 210, 220, 230, . . . that will be described below. In response to client 401's manipulation requests, manipulation properties server 100 provides manipulation services to client 401 by accessing storage mass 200. Similarly, and possibly simultaneously, a client 402 running a Java application program can use RMI via an RMI interface to interact with properties server 100 and manipulation of data based on information stored in storage mass 200. Finally, a third client, running a CORBA application 403 may also request manipulation service on data related to, for example, Wireless Ordering. Again, manipulation properties server 100 accesses storage mass 200 and performs a manipulation service for client 403.

The manipulation data may be stored in a format such as Oracle or a Lightweight Directory Access Protocol (“LDAP”). The information may be stored in another location or may be shared with other businesses. Preferably, manipulation data is stored in a table based system, more preferably in an Oracle database 200. As will be appreciated by those skilled in the art, use of an Oracle database allows for good performance, data integrity, and a wide variety of data management tools to administer the configuration data via an administration system 300. As will also be appreciated by those skilled in the art, Oracle database 200 may be represented by two or more databases located in separate geographical locations.

FIG. 2 depicts a more specific embodiment and example of the present invention, wherein the database 200 consists of a table-based system of rules organized into three hierarchically-organized views: FIELD, CLASS and GLOBAL. The three views allow a hierarchical management of the manipulations to be performed on data fields received from the client server 400. In the preferred embodiment, the three views are FIELD, CLASS and GLOBAL in order of precedence. Of course, the number of views may vary depending on the client's needs. Other embodiments of the present invention include four or more views.

Each of the FIELD, CLASS and GLOBAL views has an execution sequence. Utilizing an execution sequence provides a layered approach, and thereby a hierarchical approach to performing manipulation requests, and yields efficient results in this embodiment. According to the execution sequence for a particular view, several manipulation methods can be orderly executed on data for a matching field.

Before providing a specific example, the FIELD, CLASS and GLOBAL views are explained below. In the preferred embodiment, the FIELD view is the highest priority manipulation. Preferably, for efficiency reasons, the least amount of data is sorted by the FIELD view. If a FIELD name for the associated application is in this table that entry will dictate the manipulations to be performed.

As an example of one embodiment of the present invention, referring to Table 1, the FIELD view contains the following data:

TABLE 1 Column Name Description Tag Name Name of data field used to locate manipulations Application Name Application tag to differentiate field names from those in other applications. Application Version Application tag to differentiate field names from those in other versions of the same application. Application User Application tag to differentiate field names from those in other instances of an application and version for different users. Execution Sequence A number designating the order of execution for the 1 or more manipulation methods for an item meeting the previous criteria. Manipulation Method The name of an existing Java method to be called with the value of the field to be manipulated. Manipulation Values Used by the manipulation method to compare to (“PARM Data”) the data value. Presence determined by manipu- lation method. Items are separated by a pre- defined character (generally a “,”) (e.g., 1, 5; 20020901, 20020601) Comment Description of desired rule. Used for documenta- tion only.

In the preferred embodiment, the CLASS view is the second-highest priority manipulation. The CLASS view is used if there is no matching entry in the FIELD view. In such a case, the manipulation application server 100 will perform a lookup on the passed field name. The manipulation application server 100 will check for class names that match the first part of the field name. An illustrative example is discussed below to describe the FIELD and CLASS view hierarchy.

EXAMPLE 1

No Addresss_(—)1.Data. A client application server 400 accesses the manipulation application server 100 with the field name of Address_(—)1. However, the user has actually input no Address_(—)1 data. Thus, there is no Address_(—)1 item in the FIELD view. There is, however, an entry in the class view for Address. Therefore the manipulation functions for the class Address will be performed on the data in Address_(—)1.

As an example of one embodiment of the present invention, referring to Table 2, the CLASS view contains the following data:

TABLE 2 Column Name Description Tag Name A generic string that will be used to match the field's name up to a defined character. (Date_1 will match up with Date) Application Name Application tag to differentiate field names from those in other applications. Application Version Application tag to differentiate field names from those in other versions of the same application. Application User Application tag to differentiate field names from those in other instances of an application and version for different users. Execution Sequence A number designating the order of execution for the 1 or more manipulation methods for an item meeting the previous criteria. Manipulation Method The name of an existing Java method to be called with the value of the field to be manipulated. Manipulation Value 1 Used by the manipulation method to compare to (“PARM Data”) the data value. Presence determined by manipu- lation method. Items are separated by a pre- defined character (generally a “,”) Comment Description of desired rule. Used for documenta- tion only.

Finally, in the preferred embodiment, the GLOBAL view is the most generic method of performing manipulation functions. Any field that does not have an entry in either the FIELD or CLASS view will be manipulated with the methods dictated for the associated application information. As this view is generic, preferably the most data is handled at the GLOBAL level, thereby improving efficiency. Examples are now discussed below describing the hierarchy between the FIELD, CLASS and GLOBAL views.

EXAMPLE 2

The field name is Residence_(—)2. There is no Residence_(—)2 item in the FIELD view. There is no Residence entry in the CLASS view. There is, however, a GLOBAL manipulation function called toUpper in the GLOBAL table for the application 400 (name, version and user) that requires data manipulation. Therefore, in this example, the data for Residence_(—)2 will be converted to all uppercase letters and manipulation properties server 100 will provide an appropriate return to client 400.

In the preferred embodiment, each of the FIELD, CLASS and GLOBAL views has an execution sequence for the associated manipulation functions that exist for that view. This provides a layered approach to manipulation. An example for describing the execution sequence is described below.

EXAMPLE 3

Field Name: Date 1.

Referring to the illustrative table below, in this illustrative example there is no match for Field Name: Date_(—)1 in the FIELD view. However, there are manipulation executions in the FIELD view table for LastDay, 4digitYear and FirstDay. The manipulation properties server 100 recognizes that the CLASS view table has a matching item called Date. An example of the CLASS view table is as follows:

Application Application Application Execution Manipulation Manipulation Tag Name Name Version User Sequence Method Value 1 Comment Date Appl1 001 EMRS1 10  LastDay Dec. 31, 2002 Date Appl1 001 EMRS1 1 4digitYear Date Appl1 001 EMRS1 5 FirstDay Jan. 1, 1996

In this exemplary example, based on the Execution Sequence of “1”, the date is first converted to a four-digit year (if necessary by manipulation method “4digityear”). Next, based on the next rule, which has an execution sequence of “5”, the date data will be converted to Jan. 1, 1996 if it is not prior to that date using the FirstDay method. Next, the date will be converted to Dec. 31, 2002 if it is after that date with the LastDay method based on the Manipulation Value 1 PARM data in the CLASS view table. Finally, the server 100 will return the converted data to the requesting client application server 400. As will be appreciated, this is an example illustrating a “CLASS” level manipulation.

The table below illustrates examples of proposed manipulation functions:

Return Type Function Name Argument 1 Argument 2 Argument 3 Argument 4 Boolean ManipulateIntegerField String Field Name Integer Field Data Integer Min Value Integer Max Value Boolean ManipulateStringField String Field Name String Field Data Integer Max Value Boolean ManipulateDateRange- String Field Name String Field Data Earliest Date Latest Date Field

FIG. 2 depicts further example manipulations performed by an exemplary embodiment of the present invention. In this embodiment, client application server Long Distance Delivery Ordering (“LD ORD”) 400 seeks to manipulate data input by a customer, such as user name, the type of service requested, the date available for service, the date of expiration related to a desired telephone service, etc. Accordingly, using a known software application protocol, application server LD ORD 400 sends manipulation requests related to the data input by a customer to the manipulation application server 100. As a first example, the user's name is tag named “User_Name” and has been input as “John Doe”. The server 100 notes that the application LD ORD, version 1.0, has generated a request for service. Accordingly, the manipulation application server 100 generates an instruction to call the FIELD view table from the storage medium 200 for User_Name. In this example, the application server 100 automatically follows the priority of rules stored and dynamically maintained in the database 500. Here, there is only one rule, i.e., one Java Function, for User_Name, which is applicable to any user of LD ORD, version 1.0. As shown in FIG. 2, the Java method associated with User_Name rule is ToUpperCase method. Accordingly, the manipulation server 100 checks to see if the input data is all uppercase while also checking for PARM data. Here, if the input data is not all uppercase, the manipulation server 100 converts the data to all uppercase for client 400 and provides an appropriate return to client 400. Of course, if the input data is all uppercase the manipulation server 100 returns an appropriate response to client 400.

Next, according to the example depicted in FIG. 2, the manipulation server 100 performs manipulation service on manipulation requests for data input by a user for date of service, which has been tagged DATE_Serv. Here, database 200 presently has no FIELD view rules for any users of LD ORD, version 1.0, data tagged DATE_Serv. However, in the preferred embodiment, the manipulation server 100 will automatically perform two of three available Java-based CLASS view functions, based on the PARM data and execution sequence of the three presently available CLASS view rules, on the data tagged DATE_Serv, thereby converting the input data 04/01/02 to 20020415. First, the server performs a 4digityear function, and then the server performs a FirstDay function. In this example, the function LastDay is not performed because the PARM data is past the input date. Here again, server 100 provides an appropriate response to client 400. As shown in FIG. 2, the application server 100 will read the execution sequences to determine which Java function to perform first. Java function 4digityear has an execution sequence of “1” and Java function FirstDay has an execution sequence of “5”. Based on this sequence of execution set forth in this CLASS view, the manipulation server 100 executes first the 4digityear function and then the FirstDay function on the data. As will be appreciated by those skilled in the art, in this example, if there were no DATE rules, manipulation application server 100 would automatically look for GLOBAL rules in the GLOBAL-view table. Of course, in other embodiments, the server 100 could prompt the user for additional information or generate prompts between class levels. In other embodiments, further services may be provided in response to manipulated data being returned to the client, such as additional data manipulations, generation of further functions, etc. In one embodiment, the manipulated data is displayed on a user's screen for approval before further processing.

Referring again to FIG. 2, next, LD ORD 400 requests manipulation service on data related to the date of availability for a requested telephone service. This data has been tagged DATE_(—)5. The priority of rules 500 indicates that presently there is one rule in the FIELD view, i.e., there is one manipulation function, for DATE_(—)5. Therefore, the manipulation application server 100 performs a FirstMonth function on the data tagged DATE_(—)5.

As shown in FIG. 2, in some instances, server 100 will have rules for specific users of specific versions of application LD ORD. Additionally, database 200 may contain various GLOBAL methods (e.g., ALL) data used by any user of LD ORD. As will be appreciated, the server 100 provides great flexibility for dynamically providing many manipulation functions for a plurality of clients.

As will also be appreciated, by utilizing a centrally located storage system of dynamically maintainable manipulation rules, the present invention provides greater flexibility than known systems. For example, in the exemplary example discussed above system administration 300 (FIG. 1) can change the PARM data for DATE_(—)5 and, accordingly, all applications 400 requesting manipulation services for data related to DATE_(—)5 are contemporaneously updated.

In some instances, the number of manipulation requests may be large depending on the number n of application clients 400 using the server 100. Constant database 200 reads may cause delays in manipulation service. Therefore, in one exemplary embodiment, the manipulation server 100 will read the database 200 data 500 into memory on startup. Updates to the manipulation rules and values stored in the data tables can occur after system start up.

Two exemplary methods to handle dynamic table updates are described below. The first method is to restart the manipulation application server 100 each night during a maintenance window. This approach is a simple restart of the manipulation server. The application itself would not have to restart since it could detect the lost connection to the manipulation server and reconnect. This would be seamless to the applications and end user of the applications. Another exemplary method involves creating a refresh function in the manipulation server 100. Preferably the server 100 will use a REFRESH_HOURS parameter. The memory tables will be updated from the database 200 based on this parameter. Preferably, the REFRESH_HOURS will be greater than 8. As will be appreciated, keeping the data 500 in the application server 100 memory will improve manipulation performance and allow or maintaining the dynamic nature of the manipulation routines.

The most generic field type in Java is the string. In the preferred embodiment, all data passed to the manipulation server 100 will be treated as a string. This will allow applications 400 to change to more generic data without impact. This embodiment will provide an interface that is generic as possible by establishing the interface as Strings (ASCII). An example of this concept is set forth below.

For example, originally a business requirement required a date value for a Date of Birth variable. The requirement for the legacy system required the date with a two-digit year. The value of the field data from the data source is “02/31/02.” However, testing with the legacy system shows that the legacy system actually needs a four-digit year. Because the application is using the manipulator server 100, a code change is avoided. Since the integer values can be type cast to String and passed to the manipulation server 100, modifications to the rules can be made quickly. Modifications to types would cause the manipulation server 100 to understand application knowledge and not data values and manipulation rules. Here, the manipulation method can be changed from 2digityear to 4digityear. Accordingly, the output dates will now have the correct format for the legacy application.

According to the present invention, since the variable is stored as a string, the client code is not affected. Changes to manipulation functions may be done without disturbing the running applications that utilize this manipulation service.

Proposed ManipulatorClient CLASS methods include:

TABLE 3 Method Return Type Arguments Description Manipulator- Manipulator- Application Name, Class constructor. Client Client Application Also used to initial- Version, ize Application data Application User for subsequent calls Manipulator- Manipulator- Class constructor. Client Client Manipulator- Manipulator- Class destructor Client Client set Application Name, Sets application data Application settings for the Version, object. Application User translate Boolean Field Name, Sends data to the Field Value manipulator server for work. If the data is successfully translated, a TRUE is returned. Other- wise; a FALSE is returned. translate MRHashTable FMHashTable Sends data to the manipulator server for work. If the data is successfully translated, a TRUE is returned. Other- wise; a FALSE is returned. RuleType Integer Field Name Gets the rule type used for manipu- lation − 0 = None, 1 = Field, 2 = Class, 3 = Global {Used primarily for development}

In one embodiment, the client servers 400 can minimize network traffic using Field Value Hashtables. As will be appreciated, this will reduce the number of transactions to the manipulation application server 100 and improve performance. One call to the server 100 can contain an entire set of data in need of manipulation. The individual manipulation statuses will also be returned in a Hashtable. Preferably, the IsValid method is used to determine if all the data passed manipulation. If not, individual methods can be checked to determine problem areas.

Proposed FMHashTable CLASS methods include:

TABLE 4 Method Return Type Arguments Description FMHashTable FMHashTable Constructor for a Field Value HashTable object. AddToSet Boolean Field Name, Add a field value pair Field Value to the FVHashTable. Return True on success. RemoveFromSet Boolean Field Name Remove a field value pair from the FVHashTable. Return True on success. MemberValue String Field Name Return the value of the specified key.

Proposed MRHashTable CLASS methods:

TABLE 5 Method Return Type Arguments Description MRHashTable MRHashTable Constructor for a Manipulator Return HashTable object. AddToSet Boolean String Field Add a field value Name, pair to the Boolean Valid MRHashTable. Return True on success. RemoveFromSet Boolean String Field Remove a field Name, value pair from the MRHashTable. Return True on success. MemberValue Boolean Field Name Return the manipu- lation status value of the specified key. IsValid Boolean Returns a True if all values for the set are True. Other- wise; returns a False.

As will be appreciated, according to the embodiments discussed above, two devices that are coupled can engage in direct communications, in indirect communications or a combination thereof. Embodiments of the present invention relate to data communications via one or more networks. The data communications can be carried by one or more communications channels of the one or more networks.

In accordance with an embodiment of the present invention, instructions adapted to be executed by a processor to perform a method are stored on a computer-readable medium. The computer-readable medium can be a device that stores digital information. For example, a computer-readable medium includes a compact disc read-only memory (CD-ROM) as is known in the art for storing software. The computer-readable medium is accessed by a processor suitable for executing instructions adapted to be executed. The term “adapted to be executed” is meant to encompass any instructions that are ready to be executed in their present form (e.g., machine code) by a processor, or require further manipulation (e.g., compilation, decryption, or provided with an access code, etc.) to be ready to be executed by a processor.

Systems and methods in accordance with the embodiments of the present invention disclosed herein can advantageously allow for efficient hierarchical management of manipulation requests to be performed on data fields. In accordance with the present invention, centrally stored manipulation functions can be manipulated as the customer desires or manipulation constraints change. Application administrators can update or change manipulation methods done on field data without a new release of code. By implementing changes to manipulation methods in the server paradigm, one change is effective for all server clients.
